This is a bit of a subjective question, but I want to run it by everyone here:
I've been thinking of building a basic linux server that would consist of one or more internal hard drives and then multiple external USB/eSATA drives on a rotating offsite backup schedule.
When I think server storage, the first thing I think is going with a RAID solution. But these days, I'm looking around at the storage sizes of individual disks and I'm questioning if RAID is even really necessary anymore.
To me, different raid configurations can give the following advantages:
- Drives raided together to appear as one huge volume
- Striped drives for increased read/write speed
- Data Redundancy
And now, the reasons I feel like raid isn't really necessary for me
- I can get individual 1.5+ TB drives, which is big enough for me for now
- I don't need amazing read/write speed on a server that is not accessed constantly by many people
- I have enough rotating data backup solutions for my server that the raid data redundancy doesn't seem necessary
I just want to run this by the SF crowd to make sure I'm not missing something obvious. It just doesn't seem like its necessary for a basic server and if anything it seems like it would be just another thing to deal with. Any opinions?
